Which three network management requirements are common practices in network design? (Choose Two)

RMON poll data collection is less commonly mandated as a standard design practice compared to SNMP polling, which is more universally deployed and referenced in network management guidelines.

Ensuring all network devices have synchronized clocks via NTP is a universal network management best practice, as it is required for accurate log correlation, event sequencing, and fault diagnosis across distributed devices.

For bursty and inconsistent KPIs, instantaneous or peak counters are more meaningful than averages, which can mask transient spikes - making this recommendation technically reversed.

Collecting SNMP poll information such as interface counters and device statistics for future regression analysis enables trend analysis and baselining, which is a standard practice referenced in network management frameworks.

Synthetic traffic validation for data plane health is a valid operational practice but is not one of the two most common baseline design requirements alongside clock synchronization and SNMP collection.

Capturing both ingress and egress flow-based packets while avoiding duplication is a complex NetFlow/IPFIX consideration, not one of the top foundational network management design requirements.
